HSBC says Middle East geopolitics and oil prices are the main drivers of the US dollar and other major G8 currencies. It points to a stronger recent link between the dollar and oil, linked to supply shocks and safe-haven flows.
The bank says market moves may depend on shipping disruption through the Strait of Hormuz and the path of oil prices. It adds that swings in geopolitical risk can push markets between “risk-off” and “risk-on”.
Oil And Dollar Link Strengthens
HSBC says lower oil could help net energy importers and support risk appetite, with “risk-on” currencies outperforming “safe-haven” currencies. It says the Japanese yen may lag, and notes intervention risk when USD/JPY is in the 158–162 range.
It says oil stabilising at $100 may reduce short-term pressure on net importers, while recession risk is described as limited and fiscal concerns may rise. Under this scenario, it expects range-bound FX with a mild tilt towards the dollar.
HSBC says prolonged disruption to oil and gas flows via Hormuz could weaken sentiment, increase safe-haven demand, and hurt net importers through terms-of-trade effects. If the dollar–oil link weakens, it says pre-conflict FX fundamentals may matter more again, and it notes the Fed is not in a rate-hiking cycle nor outright hawkish.
We believe that Middle East geopolitics and oil prices are the main things moving foreign exchange markets right now. Market direction will likely depend on practical signs, such as shipping disruptions in the Strait of Hormuz, which directly impact oil prices. As these tensions rise and fall, oil can move sharply, and so can market sentiment.
Signals To Watch In Markets
Since the conflict intensified in late 2025, we have seen the US dollar and oil prices move more closely together. With Brent crude recently trading near $98 a barrel and the Dollar Index (DXY) firm above 106, this reflects both worries about energy supply and investors seeking the dollar as a safe haven. This is a change from the behaviour we observed for most of last year.
A prolonged disruption would likely hurt countries that are net energy importers, such as those in the Eurozone and Japan. Data from the first quarter of 2026 already shows a rising energy import bill for the European Union, which may continue to weigh on the euro. Traders should watch for any escalation that could justify strategies betting on further EUR/USD weakness.
The Japanese yen is particularly weak, but caution is needed as USD/JPY now trades above 159. We remember that similar levels around 160 prompted intervention from Japanese authorities back in late 2025. This risk makes it tricky to bet on continued yen weakness, as a sudden government action could cause a sharp reversal.
If we see the positive link between oil and the dollar begin to break, it may be an early sign that old market behaviours are returning. For instance, a drop in oil prices back toward the $85 levels seen late last year would likely boost risk appetite and benefit commodity currencies. Watch for sustained, peaceful passage of tankers through the Strait of Hormuz as a key signal for this shift.
We should also consider that factors are in place that may limit broad-based dollar strength. The Federal Reserve is not raising interest rates, and while March’s inflation data came in a bit high at 3.1%, the Fed has not turned more aggressive. This stance could cap the dollar’s rally if the immediate geopolitical fears begin to fade.
